Great product! I have been working out for many years and PLANK BUDDY has been a great addition to my routine! I thought I had pretty good form but quickly realized I couldn’t hold that form for very long. PLANK BUDDY is so easy to use and is a great way to work on form and proper body mechanics. I can really tell a difference in my core strength. I use the plank buddy at home, in the gym and bring it with me when I travel.
